Abstract

Le problème décrit par la présente invention est que des particules de composite de graphène/matériau actif d'électrode positive polyanionique classiques n'ont pas été en mesure d'atteindre une haute conductivité puisque la surface de contact entre le graphène et le matériau actif d'électrode positive polyanionique est faible. La solution selon la présente invention porte sur un procédé de production de particules de composite de matériau actif d'électrode positive polyanionique, comprenant : une étape 1 consistant à former, par mélange d'un précurseur de matériau actif d'électrode positive polyanionique et d'un oxyde de graphite, des corps granulés de composite précurseur contenant chacun une particule précurseur de matériau actif d'électrode positive polyanionique dans un oxyde de graphite ; une étape 2 consistant à chauffer à une température de 500 °C ou supérieure les corps granulés de composite précurseur dans une atmosphère inerte ou dans une atmosphère réductrice. En ce qui concerne l'intensité de diffraction des rayons X des corps granulés de composite précurseur, l'intensité maximale du pic de diffraction des rayons X sur la base du matériau actif d'électrode positive est inférieure à 50 % de l'intensité maximale du pic de diffraction des rayons X sur la base des matériaux autres que le matériau actif d'électrode positive. En ce qui concerne l'intensité de diffraction des rayons X des particules de composite de matériau actif d'électrode positive polyanionique, l'intensité maximale du pic de diffraction des rayons X sur la base du matériau actif d'électrode positive est supérieure ou égale à 50 % de l'intensité maximale du pic de diffraction des rayons X sur la base des matériaux autres que le matériau actif d'électrode positive.
